Description

Technical Field

[0001] This utility model relates to the field of mechanical tool technology, specifically to a multi-layer pipeline layout structure for an excavator. Background Technology

[0002] Excavators are a type of construction machinery widely used in earthmoving. The front of an excavator is connected to attachments such as a bucket, breaker, and hydraulic shears via a boom. To enable the movement of these attachments, multiple hydraulic steel pipes are typically installed and controlled by hydraulic cylinders at the ends.

[0003] The inventors discovered the following technical problems during the installation of attachments and piping:

[0004] With the increasing digging capabilities of excavators, various attachment pipes need to be installed on the boom, sometimes reaching more than a dozen. However, existing excavator booms can only accommodate 6-8 hydraulic lines. During installation, the hydraulic lines are installed side by side on the surface of the excavator boom using pipe clamps. After installation, the hydraulic lines form a single layer along the boom height. When additional lines need to be installed, they are placed on both sides of the boom or extend beyond the boom width. This results in the external hydraulic steel pipes being damaged by the construction object during actual operation. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer pipeline layout structure for excavators, which can at least solve one of the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model proposes a multi-layer pipeline arrangement structure for an excavator, including a boom. Several spliced ​​pipe clamps are arranged along the top of the boom. The spliced ​​pipe clamps include a single-layer pipe clamp and an L-shaped pipe clamp. The single-layer pipe clamp is provided with a convex block and a C-shaped cover plate. A hydraulic pipe I is symmetrically placed on both sides of the convex block. A C-shaped cover plate is provided on the top of the hydraulic pipe I. The C-shaped cover plate is fixed to the convex block by bolts. The top of the C-shaped cover plate is fixedly connected to the L-shaped pipe clamp by bolts. The L-shaped pipe clamp is used to install hydraulic pipe II through a through hole.

[0007] Further configuration: the convex block is fixed to the top of the boom, and the bottom of the convex block is welded to the top of the boom.

[0008] Further configured, the convex block includes a base, a stop is vertically mounted on the base, the stop is centrally located above the base, and the stop is integrally mounted with the base.

[0009] A further configuration is provided where a stepped groove is provided between the stop block and the base, and a hydraulic pipe I is placed on the stepped groove.

[0010] Further configuration includes a first screw hole extending through the stop block and the base, a C-shaped cover plate on the top of the stop block, and an L-shaped pipe clamp on the top of the C-shaped cover plate.

[0011] Further configuration: the C-shaped cover plate has a second screw hole corresponding to the first screw hole, and the first screw hole and the second screw hole are coaxially arranged.

[0012] Further configured, the L-shaped pipe clamp includes a horizontal plate and a vertical plate, wherein the horizontal plate has a third screw hole corresponding to the second screw hole.

[0013] A further configuration is provided, wherein a pair of through holes are provided in the vertical plate, and hydraulic pipe II is installed through the through holes.

[0014] Further configuration: the central axis of hydraulic pipe II is perpendicular to the vertical plate.

[0015] Further configuration: the L-shaped pipe clamp is perpendicular to the C-shaped cover plate, and the central axis of hydraulic pipe II is parallel to the central axis of hydraulic pipe I.

[0016] The beneficial effects of one or more of the above technical solutions:

[0017] The piping is organized by arranging and setting up spliced ​​pipe clamps. The spliced ​​pipe clamps include a first layer of pipe clamps and an L-shaped pipe clamp set in the second layer. The first layer of pipe clamps is equipped with a convex block and a C-shaped cover plate. Each step at both ends of the convex block can hold a hydraulic pipe I. After the C-shaped cover plate is set on the top of the hydraulic pipe, the C-shaped cover plate and the L-shaped pipe clamp are pressed onto the convex block by bolts to complete the fixation of the first layer of piping. Then, the L-shaped pipe clamps are used to install hydraulic pipe II through the through hole, so that the hydraulic piping can be arranged in two rows, one above the other, and the hydraulic piping will not appear on both sides of the boom.

Detailed Implementation

[0023] The specific implementation of this embodiment will now be described with reference to the accompanying drawings.

[0024] Reference Figure 1 and Figure 2 This utility model proposes a multi-layer pipeline layout structure for excavators, referring to... Figure 1 The system includes a boom 1, and several spliced ​​pipe clamps 2 are arranged along the top of the boom 1. The spliced ​​pipe clamps 2 include a layer of pipe clamps 3 and L-shaped pipe clamps 4. The layer of pipe clamps 3 is provided with a convex block 5 and a C-shaped cover plate 6. A hydraulic pipe I 7 is symmetrically placed on both sides of the convex block 5. The top of the hydraulic pipe I 7 is provided with a C-shaped cover plate 6. The C-shaped cover plate 6 is fixed to the convex block 5 by bolts 8. The top of the C-shaped cover plate 6 is fixedly connected to the L-shaped pipe clamp 4 by bolts 8. The L-shaped pipe clamp 4 is installed with a hydraulic pipe II 10 through a through hole 18.

[0025] The convex block 5 is fixed to the top of the boom 1, and the base 11 of the convex block 5 is welded to the top of the boom 1. Along the width direction of the boom 1, several convex blocks 5 are spaced apart to create gaps between the pipes and prevent the pipes from being squeezed and rubbed.

[0026] The convex block 5 includes a base 11, on which a stop 12 is vertically arranged. The base 11 is horizontally welded to the top of the boom 1, and the stop 12 and the base 11 are an integral structure, which enhances the connection strength between the stop 12 and the base 11.

[0027] A stepped groove is provided between the stop block 12 and the base 11. The hydraulic pipe I7 is placed on the stepped groove. Since the length of the base 11 is greater than the thickness of the stop block 12, the stop block 12 is centrally located on the base 11, dividing the base 11 into two parts, forming two stepped grooves. During installation, the hydraulic pipe I7 is placed on the stepped groove to ensure that the hydraulic pipe I7 is spaced apart, thus completing the arrangement of the first layer of hydraulic pipe I7.

[0028] A first screw hole 13 is made through the stop block 12 and the base 11. A C-shaped cover plate 6 is set on the top of the stop block 12. An L-shaped pipe clamp 4 is set on the top of the C-shaped cover plate 6. A second screw hole 14 is made on the C-shaped cover plate 6 corresponding to the first screw hole 13. The L-shaped pipe clamp 4 includes a horizontal plate and a vertical plate. A third screw hole 15 is made on the horizontal plate corresponding to the second screw hole 14. The first screw hole 13, the second screw hole 14 and the third screw hole 15 are coaxially arranged. After the first screw hole 13, the second screw hole 14 and the third screw hole 15 are simultaneously connected by bolts 8, the C-shaped cover plate 6 and the horizontal plate are fixed on the convex block 5. Under the action of the bolts 8, the C-shaped cover plate 6 presses down on the hydraulic pipe I7 on the stepped groove, and fixes the hydraulic pipe I7 on the stepped groove. At the same time, the L-shaped pipe clamp 4 is fixed on the C-shaped cover plate 6 and the convex block 5 by the bolts 8, forming a two-layer pipeline structure.

[0029] A pair of through holes are made in the vertical plate, through which hydraulic pipe II10 is installed. The central axis of hydraulic pipe II10 is perpendicular to the vertical plate. L-shaped pipe clamp 4 supports the second layer of hydraulic pipe II10, so that the pipeline can form two layers. L-shaped pipe clamp 4 is perpendicular to C-shaped cover plate 6. The central axis of hydraulic pipe II10 is parallel to the central axis of hydraulic pipe I7. After installation, hydraulic pipe I7 and hydraulic pipe II10 are arranged in two parallel rows above boom 1.

[0030] The installation process for the two rows of pipes is as follows:

[0031] A hydraulic pipe I7 is placed on each of the two stepped ends of the convex block 5. Then, the second screw hole 14 of the C-shaped cover plate 6 is placed in line with the first screw hole 13 of the convex block 5, and the L-shaped pipe clamp 4 is placed in line with the second screw hole 14. Then, the screw holes are tightened to complete the fixing of one layer of pipeline. The L-shaped pipe clamp 4 is installed with hydraulic pipe II10 through the through hole, so that the hydraulic pipeline can be arranged in two rows, and the hydraulic pipeline will not appear on both sides of the boom 1.

[0032] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
